b)11×33×2+7√2=726+7√2
c)√2
d)2√6+2√6+6√15+8√9=4√6+6√15+24
e)3√2+3+2√3+3√3=3√2+3+5√3

Answer 2

$a).2 \sqrt{4} +3 \sqrt{9} -3=2 \cdot 2+3 \cdot 3-3=4+9-3=13-3=10 \\ b).11 \sqrt{2} \cdot 33 \sqrt{2} +7 \sqrt{2} =726+7 \sqrt{2} \\ c).11 \sqrt{4} :11 \sqrt{2} = \sqrt{2} \\ d).2 \sqrt{2} ( \sqrt{3} + \sqrt{3} )+2 \sqrt{3} (3 \sqrt{5} +4 \sqrt{3} )= 2 \sqrt{2} \cdot 2 \sqrt{3} +6 \sqrt{15} +24= \\ =4 \sqrt{6} +6 \sqrt{15} +24 \\ e). \sqrt{18} + \sqrt{9} +2 \sqrt{3} + \sqrt{27} =3 \sqrt{2} +3+2 \sqrt{3} +3 \sqrt{3} =3 \sqrt{2} +3+5 \sqrt{3}$
